` 2 claims. (ol. 76-6si I Still another object of the invention is to provide means for varying the throw of the departing from the spirit of `the invention as d claime Referring to the drawing, Figure |1 is a front elevational view of a saw Fig. 3 is a side elevational View of the saw set. `g. 4 is a sectional viewtaken on line 4--4 ofFig.`1. Referring to the set comprises the -base 5 which 1s provided with set to a supporting` surface.

The base is constructed preferably of channel bar material, and when positioned on a supporting surface has its open side disposed towards the supporting surface.

One edge of the base is provided with a recess 1 which is formed with a downwardly inclined bythedrawing.- I I This U -shaped bracket I I is formed withaligning openings in the arms thereof, which openings downwardly.

Mounted on the upper arm of the U-shaped bracket II, is the se screw I 8 which is so dis- This set screw I8, because of its position on the U-shaped bracket, acts as a stop to limit the pivotal movement of the operating consequently limiting the movement of the plunger I2. This is necessary, since of saws of various sizes.

The reference character I9 indicates a pivoted gauge arm which is provided with the forr screw in r the plate *9 :teeth are positioned against the set screw overthe upper endof the plunger I2,

wardly extended lip 20 that is designed to fit in the gullet between the teeth of the saw, so that When the saw is positioned with the lip 20 within the gullet between teeth, the saw will be correctly located so that the tooth to be set will fall directly over the recess 1 and under the plunger I2 to insure the true operation of the setting of the saw tooth.

The set screw 2I connects the pivoted gauge arm ISI-,to the'verticalplate 9 and affords means whereby the arm `I9vrnay be swung laterally to adjust the position of the arm for a particular type of saw tooth.

Also positioned in plate 9, is the screw a threaded opening of the 22, which screw 22 moves into the notch 23 formed in one edge of the base or anvil 5, the set screw prov-idinga stop against which teeth of the saw may engage to permit the saw toothed saws. By moving the set screw 22 towardsithezplate 9,it-will be obvious that the @clearancebetweenthe pointed' ends of the saw :teeth .of the saw maybe increased to compensate for large toothed saws, While by moving the set base-5, the distance betweenthe may be reduced so that when the 22 the fsawteeth being. set will be held securely7 during ithe .setting operation.

In operation, asaw ,to beset is vpositioned with altooth resting directly over the recess l. be understood that the pivoted farmIS and 1screw22 will be adjusted so that whena saw-.toothispositioned over the recess, -thevsaw ,will :be properly held in place on the base against movement. The operating reel I zisnowswung to a position to the right of the sawset, whichimovementfcauses the wide por- `tion'of the pivoted endof the lever I5 to move moving Athe plunger I2 downwardly against the action of the coiled spring I4 and exerting pressure on the tooth forcing the tooth intothe recess, mov- ,ing the-tooth laterally of the saw blade providing fthe,-1 proper set for thetooth.

be understood that the saw is base, skipping the adjacent saw .It will then f moved alongA the tooth. -Withz the saw tooth adjacent to the tooth skipped, disposed directly under the plunger I2 the recess, the lever 1s again moved downwardly to the right, causing the Vplunger I-2"to'fpress the sawtooth lying directly thereunder, toset the rsaw tooth.

vIt will be obvious that'when alternating saw 5 teeth of a saw .blade have will be reversed and theremaining l'the same -manner as described.

been set, the saw teeth set in set to be used with fine or largey `wardly away from said anvil,

It is believed in ing and description,

what is edge thereof, a plate-rising `frorni-one side edge of the anvil adjacent to the notch and spaced from the edge of the anvil, a vertically movable plunger mounted on the plate, a spring mounted on said plunger normally biasing the plunger upoperating directly over vthe notch with one end of the plunger movable into the notch adapted to engage and set a saw tooth positioned over said notch, lever pivotally mounted on the plate movable into engagement with the plunger effecting downward movement of the plunger against the saw tooth,y and a vertically adjustable screw mounted on the plate lying in the path odownward travel of said lever for restricting downward movement of the lever regulating 1 thesetting of the saw 'tooth positioned thereunder.

2. In a saw set, an anvil having a notch formed adjacent to one edge thereoi, a vertically movable plunger operating directly over said notch for engaging the teeth of a saw resting over said notch, a pivoted gauge arm disposed'vertically andisecured to said plate disposed inwardly terminating adjacent-to the anvil, a lip extending forwardly from said gauge arm adapted to engage between teeth oi the saw.being set, normally holding the sawagainst longitudinal movement on said anvil, and anadjustable member for engaging the teeth ofthe saw restricting movement of the teeth towards said plate during the tooth settingoperation.
